Reggae style patenting advice - getting rich through IP

UB 40, the Reggae band founded 1978 in Birmingham, released "Tell it like it is", in 1986.

The song offers several anti-political statements, and addresses an important point of patent systems: making applicants rich. The following snippet alludes to this topic:

if you don't patent it You nah see a cent You have no money fi go pay up your rent If you crash fi your car Or you in an accident

Also, the rest of the song text is good reading and opens a lot of space for political and ethical discussions.

Ain't it surprising that even Reggae addresses da patent system?
